Patented Nov. 1, 1932 CARL s. MOLITOR, or DOBBS FERRY, NEW YORK APPARATUS FOR .THE DELIVERY OF MATERIALS Application filed July 25,

This invention relates to apparatus for use in connection withthe dispensing of materials such as liquids, viscous substances, etc., and has for oneof its objects the provision of an apparatus which isof such a character as to enable the material to be dispensed accurately in predetermined amounts. e

invention may be incorporated as a built-in or unitary'part of the container, or

by way of a separate device adapted to be applied to 'a con tain er.

More specifically the present invention provides a construction embodying, when attached to a container, a measuring chamber with a closure at the discharge end thereof and a valve at the lower or inner end, the closure and valve being connected to each other in such fashion that in operation the measuring chamber after filling is closed off from the main partof the container to preventthe entry of anymore material thereinto until after the measuring chamber has been emptied and the container again sealed.

As indicated above my apparatus is capable of use with various materials, such as liquids, viscous substances, etc.

In the drawing accompanying this application I have shown several embodiments of myinvention i Fig. 1 is a part sectional elevational view of an embodiment of my invention suitable for collapsible tubes containing viscous material Fig. 2 is another view Fig. 1; p

Fig. 3 is a view of the valve of Figs. 1 and 2; Figs. 4 and 5* are part sectional elevational views of a further. embodiment of my invention as applied to collapsible tubes; and

' Figs. 6, 7 and 8 are a further embodiment of the invention.

In the embodiment of my invention as shown in Figs. 1 and'2, 17 designates a collapsibletube or container provided with a reduced outlet or neck 18 having a valve seat 19 in the interior thereo f adjacent its outer end. The extreme outer end of the neck 18 is slightly beveled as shown at 20, this beveled portion receiving closure member 21 similarly bev-- eled. Integral with this closure member is the apparatus of 1931. Serial No. 553,055.

valve rod 22 to the lower end of which is attached a valve 23 for the said outlet, the valve being offset with respect to the valve rod. The rod 22 adjacent its union with the closure member 21 is provided with a locking lug 24 u the upper'face of which is slightly inclined downwardly as shown at 25. This lug is 7 adapted to engage the valve seat 19 so as to hold the valve 23 in open position and the closure member21 in closed position. no

1 In operation when pressure is applied to the tube 17 the material in the tube or container moves upwardly or outwardly and exerts a pressure against the slanting lower surface 27 of the valve 23. This pressure forces the .5 valve 23 to one side to bring the lug 24 beneath the seat 19 in the tube neck and hold the closure member closed until the measuring chamber 26 provided by the reduced outlet 18 of the container is filled. lVhen this chamber is filled the pressure 011 the material is then transmitted to the bottom of the closure member 21 and by reason of the engage ment or" the lug 24 with the edge of the valve seat 19 the closure member 21 will be moved outwardly slightly and caused to tip as I have attempted to illustrate in Fig. 2, the tapered sides of the closure member permitting of this tipping movement. This tipping of the closure: member will carry the lug 24 from beneath the edge of the valve seat 19 and permit the closure member and the valve 23 to move outwardly of the container to effect a discharge of the measured quantity of mate rial in the measuring chamber 26, the valve 23 moving outwardly of the tube neck until it seats on the seat 19. I i

hen the closure member 21 is again moved to its initial position on the next operation any pressure under which the material in the container may be at the moment is prevented from raising the clos'ure member because of the engagement of the locking lug 24 with the edge of the valve seat 19.

In some instances it is desirable to direct the discharging material as it leaves the container and in this connection in Figs. 4 and 5 I have provided a discharge valve 28 additional to the members just referred to in connection with Figs. 1 and 2. It will be seen from Figs. 4 and 5 that this discharge valve is provided with a discharge port- 29. This valve may be in the nature of a washer fitting the tube neck 18 and with a hood designated 30 in which is formed the discharge port 29. The rod 22 passes freely through this dis charge valve as plainly illustrated in the drawing. The operation of this embodiment of my invention is the same as that of Figs. 1 and 2, the discharge valve 28 moving upwardly as the material is discharged from the meas ring chamber 26, the port 29 being full open only when this valve strikes the seat 19 in the tube neck. In the embodiment of my invention illustrated in Figs. 6. 7 and 8 I provide an arrangement in which the reduced outlet 32 of a collapsible container 33 is provided adjacent its upper or delivery end with a seat 34L. In the outlet of the container I provide a combined'closure and discharge member designated 35 which .is provided with a discharge port 36. Passing freely through the combined closure and discharge member 35 is a rod 37 to the lower end. of which is afixed a valve or piston 38, the rod being offset relativelv to this valve or piston. This rod 37 is provided with a locking lug designated 39 which when the rod is in its inner position locks or is caught under the edge of the seat 34. A stop 40 is provided on the upper end of this rod 37 to limit the inwardmovement of the rod. In operation when the tube 33 is pressed or collapsed the material in the tube will be fo ced into the measuring chamber 41 provided b the reduced outlet of the container and against the bot om of the combined closure and discharge member 35 to move the same outwardlv until fur her outw rd movement is stopped bv contact of this member with the seat 34. It is to be noted that the rod 3 is reduced as shown at 42 and as the closure and discharge member 35 moves ou wardlv abreast of th s reduced portion 42 of the rod 37 the latter. when the lower end of the closure and discharge m mber rides over he incl ned lowe su fa e of theloclrin shonld ll move. laterallv to move the loclzin n shouL er 3 om beneath the stop or shoulder 34- ne in tting the rod 37 and the attached valve r piston 38 to move outwardlv to close the inner end of the container outlet. t e mat o ah ad of the valve being orced out of the con ainer thrmmh +1 port 36 i H binod closure and d scharge member 35. The parts finallv reach the position shown in Fi 6. This is the closed position. and he pa ts main in this position until another dischar e of the material is desired. It will be seen that in this position no material. can issue from the container. and pressure on the container below the neck will only seat the closure and discharge member 35 and the valve 38 more tightly. When another discharge is desired the parts are first pushed inwardly to the position of Fig. 7. During the inward movement of the parts, when the inclined lower surface of the locking shoulder 39 rides over the top of the neck 32, a slight tipping movement is imparted to the valve 38. The pressure of the material on the bottom of the valve tends to resist this tipping, since the valveis eccentric with respect to the valve rod. Therefore, when the locking shoulder 39 passesbelow the seat 34:, this pressure is sufiicient to move the locking shoulder into its locked position beneath the seat 34, as shown in Figs. 7 and 8.

- From all the foregoing it will be seen that I have provided a construction adapted for application as an attachment to existing containers or to be built in as an'integral part of a container by which materials may be dispensed in measured quantities.

It will be understood of course that my invention above described may be varied in its details within the spirit and scope of my invention. It is also to be appreciated that my invention may be embodied in the form of a measuring chamber adapted to be screwed upon the neck of existing containers.

What I claim is 1. In combination a collapsible container having a reduced outlet. a combined closure and discharge member for the outer end of said outlet, a rod mounted for movement relatively to said member, a valve attached to said rod, a'lug on said rod, a stop engaging said lug for initially holding the valve in open position relatively to said outlet, pressure on the container automatically unlocking said rod and moving the valve outward to discharge material ahead of the valve, until the valve engages said stop. the valve in stopped position preventing further discharge of material from the container.

2. In a device for dispensing materials, the combination of a collapsible container having a reduced outlet. a ported discharge member for said reduced outlet movable outwardly of said outlet, a seat for limiting the outward movement of said ported discharge member. a valve for said outlet. automaticallv releasable locking means for retaining said valve in open position initially. pressure on said container effecting outward movement of the said ported discharge member and relative outward movement of the said valve member. thereby effecting discharge of material from the container through the ported discharge member. and finallv sealing of the container against furth er discharge.

3. In apparatus for dispensing material in measured quantities, the combination of a collapsible container having a reduced outlet, a ported discharge member movable longitudinally of said reduced outlet, a valve piston initially adjacent the inner end of the reduced outlet and adapted upon outward movement of the ported discharge member to close off the inner end of the said outlet, continued outward movement of said valve piston discharging the contents of the outlet through the discharge member, a rod carrying said valve piston, locking means for said rod automatically released on outward movement of the discharge member to permit the valve piston to move forward to discharge the material ahead of it through the ported discharge member, the valve in its extreme outer position sealing the container.

4. In apparatus for dispensing materials in measured quantities, the combination of means providing a reduced outlet, a valve for said outlet, means for locking the valve in open position until the outlet has been filled, pressure on the material being dispensed effecting an unlocking of the valve and outward movement thereof to close the inner end of said outlet while effecting discharge of that portion of the material in the outlet ahead of said valve.

This specification signed this 24th day of July, 1931.
